At some point, Bertram was abandoned here and nature overgrew the mine and all the leftover scrap. Many years later, Toby discovered the mine when he took Sir Topham Hatt and his grandchildren exploring. Whilst on guard one night, Toby found Bertram, now they, Skarloey and Rheneas take visitors to and from the attractions that have been built on the site. There is also a small station build at the mine.
